LIGHTING vegaled on board

Product catalog summary

Introduction
This document discusses the properties and advantages of MC-PCB (Metal Core - Printed Circuit Board) materials, specifically designed for high power LEDs. The focus is on optimizing heat management and enhancing light output by using aluminum-based PCBs with highly reflective surfaces.

Specifications
The MC-PCB substrate offers:

Extremely high total reflectance through PVD treatment.
High spectral uniformity and optical performance.
High environmental stability and optimum heat management.
Available in various thicknesses.

Product Variants

VLB198: Provides over 98% reflectivity across the full output spectral range, enhancing LED luminaire performance compared to silver-plated copper PCBs.
VLB195: Offers 95% reflectivity, optimized for outdoor lighting in aggressive conditions.

Reflective Properties
The products incorporate silver in a sophisticated PVD multilayer structure, ensuring excellent color rendition and a slightly warmer light due to a faint yellow hue reflectance at shallow angles.

Technical Data

VLB195: 95% total reflectance, >90% specular reflectance, thickness range 0.75 - 1.00 mm, heat conductivity 220 W/mK.
VLB198: 98% total reflectance, >93% specular reflectance, thickness range 0.75 - 1.00 mm, heat conductivity 220 W/mK.

Environmental Tests
Both VLB195 and VLB198 demonstrate excellent stability in temperature resistance, humidity tests, and mixed gas tests, with minimal total reflectance reduction.

Reflectivity Characteristics

Specular Reflectance: Light reflected at an angle equal to the angle of incidence.
Diffuse Reflectance: Amount of scattered light.
Total Reflectance: Total light reflected as a percentage of incoming light.

Certifications
The products are certified under ISO 9001:2008, ISO 14001:2004, and BS OHSAS:2007, ensuring quality and environmental management standards.

Catalog excerpts

Metal Core-PCB is an MC-PCB (Metal Core - Printed Circuit Board) material developed for high power LEDs. To achieve an optimum heat management and increase the light output of the whole LED luminaire, it is advantageous to mount the LED chip on an aluminium based PCB coated with a highly reective surface. fulls all the requirements of an ideal modern MC-PCB substrate: Extremely high total reectance through PVD treatment High spectral uniformity High optical performance High environmental stability Optimum heat management Various thicknesses (VLB198), with over 98% reectivity across the full output spectral range for all types of LED, is the ultimate aluminium lighting reector, greatly increasing the light performance of a LED luminaire, compared to a silver plated copper PCB. (VLB195) with 95% reectivity is an optimised solution for outdoor lighting where more aggressive conditions are encountered.
